我制作了自定义用户模型。
class CustomUserManager(BaseUserManager):
def _create_user(self, email, username, password, first_name, last_name, date_of_birth, gender, mobile_number, is_active, is_admin, is_superuser):
if not email:
raise ValueError('Email must be set')
email = self.normalize_email(email)
user = self.model(
email=email,
username=username,
first_name=first_name,
last_name=last_name,
date_of_birth=date_of_birth,
gender=gender,
mobile_number=mobile_number,
date_joined=timezone.now,
is_active=is_active,
is_admin=is_admin,
is_superuser=is_superuser,
)
user.set_password(password)
user.save(using=self._db)
return user
def create_user(self, email, username, password, first_name, last_name, date_of_birth, gender, mobile_number, **extra_fields):
user = self._create_user(email, username, password, first_name, last_name, date_of_birth, gender, mobile_number, True, False, False, **extra_fields
)
user.save(using=self._db)
return user
def create_superuser(self, email, username, password, first_name, last_name, date_of_birth, gender, mobile_number, **extra_fields):
user = self._create_user(email, username, password, first_name, last_name, date_of_birth, gender, mobile_number, True, True, True, **extra_fields )
user.save(using=self._db)
return user
class CustomUser(AbstractBaseUser, PermissionsMixin):
email = models.EmailField(_('email address'), max_length=254, unique=True)
username = models.CharField(_('user name'), max_length=254, unique=True)
first_name = models.CharField(_('first name'), max_length=30)
last_name = models.CharField(_('last name'), max_length=30)
date_of_birth = models.DateField()
gender = models.CharField(choices=GENDERTYPE, max_length=1)
mobile_number = models.IntegerField(unique=True)
date_joined = models.DateTimeField(_('date joined'), default=timezone.now)
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)
objects = CustomUserManager()
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['username', 'first_name', 'last_name', 'date_of_birth', 'gender', 'mobile_number']
def get_full_name(self):
return self.email

迁移成功完成。但是，在尝试创建超级用户时，我收到的错误是这样的：
(djangoweb) vagrant@precise32:/vagrant/djangoweb/myproject$ python manage.py createsuperuser

User name: testme
First name: test
Last name: me
Date of birth: 1111-11-11
Gender: 1
Mobile number: 1111

我认为这是因为与日期时间有关的事情，但我无法弄清楚出了什么问题。我在这里做错了什么？
答案 0 :(得分：2)
我不是肯定的，但我猜测了这一行：
user = self.model(
#other code
date_joined=timezone.now,
#other code
)
您将函数作为date_joined的值而不是实际值timezone.now（）传递。这是在您拥有的模型声明中执行此操作的正确方法，但我相信您在制作对象时需要实际值。
user = self.model(
#other code
date_joined=timezone.now(),
#other code
)
当然，由于您指定了默认值，因此您可以将其完全保留，并让模型填写默认值。
